Gratitude = Goodness

Want a natural high? Just tell someone thank you (sincerely). From Psychology Today:

Gratitude is a sentiment we'd all do well to cultivate, according to positive psychologists, mental health clinicians and researchers who seek to help everyone create more joy in life. Feeling thankful and expressing that thanks makes you happier and heartier—not hokier.

The biggest bonuses come from experiencing gratitude habitually, but natural ingrates needn't despair. Simple exercises can give even skeptics a short-term mood boost, and "once you get started, you find more and more things to be grateful for," says Robert Emmons, a leading gratitude researcher at the University of California at Davis.

In gratitude letters like those penned by Peterson and his students, writers detail the kindnesses of someone they've never properly thanked. Read this letter aloud to the person you're thanking, Peterson says, and you'll see measurable improvements in your mood. Studies show that for a full month after a "gratitude visit" (in which a person makes an appointment to read the letter to the recipient), happiness levels tend to go up, while boredom and other negative feelings go down. In fact, the gratitude visit is more effective than any other exercise in positive psychology.
